Why The Bioscanner Matters
Subnautica players naturally scan wrecks and technology, but biological materials can be just as important. The Bioscanner helps turn unknown plants, creatures, and samples into usable information.
If a recipe mentions a strange organic material, scanning the route is often more useful than searching for a loose pickup.
What To Scan First
Scan unfamiliar plants near objective routes, creature remains or behavior zones, and unusual biological structures. If a route has infected growth, alien flora, or specimen-like objects, slow down and scan.
How To Use It In Co-op
In co-op, assign one player to scanning while others gather or mark the route. That prevents the group from leaving a biome before unlocking key biological information.
How To Use This Page
Use this page to decide whether a tool solves your current route problem. Equipment pages should answer what the item does, when it becomes worth crafting, and what route it unlocks or makes safer.
Use current in-game unlocks first, then official updates and dated community route evidence.
Before You Act On This Guide
- Confirm the tool's unlock or fragment route in your current build.
- Check the material chain before spending rare resources.
- Carry the tool only when it solves the trip you are about to take.
- Pair tools with route markers, storage, and return planning.
If the tool does not unlock a route, improve safety, or solve a craft, postpone it and keep materials flexible.
